ᐅ Pulling cables through a conduit (or duct).

Good morning everyone,

I have the following issue. I installed a conduit with an internal diameter of 100mm (4 inches) between the house and the garage.

Inside this conduit, there is already a cable 5*16, a double network cable, and a coaxial cable. The electrician who pulled these cables through back then also pulled a draw wire.

Now, over the weekend, we wanted to pull an additional cable (doorbell) through, but the draw wire must be stuck somewhere, so we cannot pull through from either side.

How can I get my cables through there now? There should still be enough space.

Thanks for your help. Attached is a picture

Can you free the pull wire by moving it back and forth? It’s probably just that the cables are crossing each other, causing the wire to get stuck. There’s still enough space in the conduit.

If that doesn’t work, try using a cable puller to insert a new wire. To pull the cable through afterward, lots of "Glubschi," as I call the cable lubricant, is very helpful. Make sure to have old towels or similar items ready so you can get a good grip on the cable while pulling.

Yes, we can move the pull wire back and forth. We have already managed to do this from both directions over several meters (yards). But then it suddenly stops, and it doesn’t move any further. I will try to insert a new wire soon.

Thanks and regards

Is it possible to move the other cables back and forth a bit? Maybe then the pull wire will be free again?

We tried again with some force. And lo and behold, we managed to pull through two connection wires attached to each other. It doesn’t go further about 2.6m (8.5 feet) towards the garage. I have now ordered an endoscope camera. Then I can take a closer look at where it’s getting stuck.

Best regards

How long is the pipe? Do you have a cable puller so you don’t have to use the wires? The cables are probably stacked on top of each other, which makes pulling difficult. Beyond 10 meters (33 feet), it really becomes challenging. As @Fummelbrett! already mentioned, it’s important to use plenty of lubricant.
